Title: Printing apparatus and ink remaining amount detection method thereof
Inventor: YOSHIKAWA HIROKAZU
IPC: B41J2/175
Filed: 2019-04-05
Abstract: To solve the problem that, when determining presence or absence of ink in an ink tank by a method using conventional electrodes, if air in an ink tank expands/contracts due to change in atmospheric pressure or change in temperature, an ink liquid surface level changes although there is no ink consumption, as a result, an error occurs in determination of presence or absence of ink.SOLUTION: A printing apparatus counts an ink remaining amount according to consumption of ink from the ink tank, updates a count value obtained by the count and stores the count value in a counter, on the other hand, and senses whether replenishment of ink to the ink tank has been done before execution of sensing of the ink remaining amount. If the sensing of the ink remaining amount is executed, the apparatus then reads out a preceding sensing result from a non-volatile memory that stores a sensing result of presence/absence of the ink, verifies transition between the preceding sensing result and a current sensing result, and controls operations of resetting and counting of the count value held by the counter on the basis of the transition obtained by the verification and a result of the sensing.SELECTED DRAWING: Figure 9
